A friend of mine told me today that he wants a cassette deck but doesn't want to spend too much on it. I've had a JVC KD-V6 for about a year that initially played and sounded great but a few months ago started slowing down and sounding weird. Are replacement belts and/or idlers still available for these decks? He doesn't have a lot to spend, I know that, so I'd like to let him have this for what I've got in it ($25), plus the belt cost. Thanks in advance for any information you can provide, I appreciate it.
